Step 4:Fill the e-liquid to the clear tank tube. Using an eliquid bottle or syringe, fill the clear tube by inserting e-liquid down the side wall (Do not fill e-liquid in the center hole, that is for air flow).

Step 5: Screw the piecemouth tip back into the clear tube again.

* Tips: Please fill the e-liquid slowly, and do not fill completely full of e-liquid, otherwise, it will be leaked into the venting hole.
